Our Telerik is Q2 2010. I recently updated our ASP.NET project from 3.5 to 4.0.
First problem I noticed is none of CustomValidators (inside ASP Panel, that is loaded through AJAX) are working. They actually render as spans, but without any of the usual attributes:
<SPAN style="VISIBILITY: hidden" id=TextBoxValidator></SPAN>
This is how they look, if I comment our RadAjaxManager:
<SPAN style="VISIBILITY: hidden" id=TextBoxValidator controltovalidate="RadTextBoxValue" clientvalidationfunction="RadTextBoxValue_Validate" validateemptytext="true" isvalid="true" enabled="false"></SPAN>
Next issue is the RadAjaxLoadingPanel that keeps spinning even after the AJAX request is completed.
When I comment out RadAjaxManager, everything seems to be working fine.

Hi Alex,
Could you please elaborate a bit more on your application. Some more information on where the Validators are added on the page, are they added in the RadAjaxManager settings and are they perform server or client validation will help us further investigate the issue. Note that there is a difference in the way the asp validators are implemented in .Net 4.0 and this also may cause the difference. I would suggest you also to test the application using regular asp UpdatePanel instead of RadAjaxManager and verify if this makes any difference.
Regarding the RadAjaxLoadingPanel could you please verify by using any debugging tools if any error appears during the ajax request, this may cause some request terminating which can be the reason for the hanging LoadingPanel.

Maria,
You are right, it was a different version of validators. We had a reference to AjaxControlToolkit.dll, and after I replaced with to the correct version(4.0), everything started to work - CustomValidators and RadAjaxLoadingPanel.
If you can please mark this thread closed.
Thanks!
